Discard vial if solution is cloudy, there is pronounced discoloration (solution may have pale-yellow color), or there is foreign particulate matter other than translucent-to-white, amorphous particles. Preparation of Solution • Allow the vial(s) to stand at room temperature for approximately 5 minutes prior to preparation of infusion. • Withdraw the required volume of YERVOY and transfer into an intravenous bag. • Dilute with 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP to a final concentration ranging from 1 mg/mL to 2 mg/mL . Mix diluted solution by gentle inversion. • After preparation, store the diluted solution either refrigerated at 2°C to 8°C (36°F to 46°F) or at room temperature of 20°C to 25°C (68°F to 77°F) for no more than 24 hours from the time of preparation to the time of infusion. • Discard partially used or empty vials of YERVOY. Administration • Do not co-administer other drugs through the same intravenous line. • Flush the intravenous line with 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP after each dose. • Administer diluted YERVOY solution by intravenous infusion over 30 minutes through an intravenous line containing a sterile, non-pyrogenic, low-protein -binding in-line filter. • When administered in combination with nivolumab, infuse nivolumab first followed by YERVOY on the same day. • When administered with nivolumab and platinum-doublet chemotherapy, infuse nivolumab first followed by YERVOY and then platinum-doublet chemotherapy on the same day. • Use separate infusion bags and filters for each infusion.

The data described in the Warnings and Precautions section reflect exposure to YERVOY 3 mg/kg as a single agent (or in combination with an investigational gp100 peptide vaccine) in 511 patients in Study MDX010-20; YERVOY 1 mg/kg administered with nivolumab 3 mg/kg in 1,362 patients in CHECKMATE-214, CHECKMATE-142, CHECKMATE-227, and CHECKMATE-743; YERVOY 3 mg/kg administered with nivolumab 1 mg/kg in 456 patients enrolled in CHECKMATE-067, CHECKMATE-040, and another randomized trial; and to YERVOY 1 mg/kg, administered in combination with nivolumab and platinum-doublet chemotherapy in CHECKMATE-9LA. Unresectable or Metastatic Melanoma The safety of YERVOY was evaluated in 643 previously treated patients with unresectable or metastatic melanoma in Study MDX010-20 [see Clinical Studies (14.1) ] . Study MDX010-20 excluded patients with active autoimmune disease or those receiving systemic immunosuppression for organ transplantation. Patients received YERVOY 3 mg/kg by intravenous infusion for 4 doses as a single agent (n=131), YERVOY with an investigational gp100 peptide vaccine (n=380), or gp100 peptide vaccine as a single agent (n=132). Patients in the trial received a median of 4 doses (range: 1 to 4 doses). The trial population characteristics were: median age 57 years (range: 19 to 90), 59% male, 94% White, and baseline ECOG performance status 0 (56%). YERVOY was discontinued for adverse reactions in 10% of patients. Table 4 presents adverse reactions from Study MDX010-20.

MSI-H or dMMR Metastatic Colorectal Cancer Treatment of MSI -H or dMMR mCRC: In Combination with Nivolumab The safety of YERVOY in combination with nivolumab was evaluated in CHECKMATE-8HW, a randomized, open-label, three arm trial in immunotherapy naïve patients with MSI-H or dMMR mCRC [see Clinical Studies (14.4) ] . Patients received one of the following: • YERVOY 1 mg/kg every 3 weeks and nivolumab 240 mg every 3 weeks for a maximum of 4 doses, then nivolumab 480 mg every 4 weeks. • Nivolumab 240 mg every 2 weeks for 6 doses, then nivolumab 480 mg every 4 weeks. • Investigator’s choice chemotherapy: mFOLFOX or FOLFIRI [see Clinical Studies (14.4) ] . In the YERVOY and nivolumab arm, the median duration of exposure to YERVOY was 2.1 months (range 1 day to 3.7 months); patients received a median of 4 doses (range 1-4). The median duration of treatment in the YERVOY and nivolumab arm was 20.5 months (range: 1 day to 35.9 months); 70% were exposed to treatment for >6 months, and 63% were exposed for >1 year. The median duration of treatment was 16.4 months (range: 1 day to 36 months) in the nivolumab-only arm; 64% were exposed to treatment for >6 months, and 54% were exposed for >1 year. Serious adverse reactions occurred in 46% of patients receiving YERVOY in combination with nivolumab, and 39% of patients receiving nivolumab alone. The most frequent serious adverse reactions reported in ≥1% of patients who received YERVOY with nivolumab were adrenal insufficiency (2.8%), hypophysitis (2.8%), diarrhea (2.0%), abdominal pain (2.0%), small intestinal obstruction (2.0%), pneumonia (1.7%), acute kidney injury (1.4%), immune-mediated enterocolitis (1.4%), pneumonitis (1.4%), colitis (1.1%), large intestinal obstruction (1.1%), and urinary tract infection (1.1%). The most frequent serious adverse reactions reported in >1% of patients who received OPDIVO, as a single agent, were intestinal obstruction (2.3%), acute kidney injury (1.7%), COVID-19 (1.7%), abdominal pain (1.4%), diarrhea (1.4%), ileus (1.4%), subileus (1.4%), pulmonary embolism (1.4%), adrenal insufficiency (1.1%) and pneumonia (1.1%). Fatal adverse reactions occurred in 2 (0.6%) patients who received YERVOY in combination with nivolumab; these included myocarditis, and pneumonitis (1 each). YERVOY and/or nivolumab were permanently discontinued in 19% of patients receiving the combination. The most frequent adverse reactions (>1%) leading to permanent discontinuation were adrenal insufficiency (1.4%), immune-mediated enterocolitis (1.1%), and pneumonitis (1.1%). Nivolumab was permanently discontinued in 13% of patients receiving single agent nivolumab.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Blood and lymphatic system disorders: hemophagocytic lymphohistiocytosis (HLH) Immune System: graft-versus-host disease, solid organ transplant rejection Skin and Subcutaneous Tissue: Drug reaction with eosinophilia and systemic symptoms (DRESS syndrome)
